[0003] Potassium (K) is present on the plasma membrane of most cell types. + ) channels are the most diverse class of all ion channels and are associated with a wide range of physiological functions, including the regulation of the electrical properties of excitable cells. The primary pore-forming (α) subunits of these highly selective cation channels are currently classified into three major structural classes based on the number of transmembrane (TM) spanning regions and pore (P) regions: 6TM / 1P, 2TM / 1P, and 4TM / 2P K +The Kv7 gene (originally called KCNQ, a name assigned by the HUGO Gene Nomenclature Committee (HGNC)) is designated by the International Union of Pharmacology (IUPHAR) as a voltage-gated K channel. + The Kv7 subfamily is composed of five homologous pore-forming α-subunits, Kv7.1-7.5, which contain voltage-gated K channels with 6TM-spanning regions (S1-S6) flanking the intracellular N- and C-terminal domains, a typical voltage sensor domain (S4) consisting of alternating positively charged residues, and a single P region located between S5 and S6 of each subunit. + They have the typical structure of Kv7 channels. The channels are formed as tetramers of primary α subunits, either as homotetramers or heterotetramers. Neurons are known to express Kv7 channels, which are composed of Kv7.2-7.5 α subunits. While some of these gene products may be exclusively neuronal, other gene products, such as Kv7.4 and Kv7.5, are found in other tissues, such as smooth and skeletal muscle.

[0004] Native M-channels, and the corresponding macroscopic M-currents, were first characterized in amphibian sympathetic neurons. M-channels activate and deactivate slowly, are active at or near the neuron's resting membrane potential, and muscarinic cholinergic agonists decrease the M-current, interacting with G-protein-coupled receptors (GPCRs) and physiological K-channels. + It was not until the cloning of this gene subfamily that the pharmacological and biophysical identity between Kv7.2 / 7.3 (and possibly Kv7.5 / 7.3) heteromultimers and the elusive "M" channels was established, providing important new evidence for their importance in neuronal regulation.

[0005] The distribution of these channels, both regionally and developmentally, as well as their biophysical properties, support their role in providing durable resistance to depolarizing excitatory influences. Under physiological conditions, as demonstrated for native M channels, they are highly effective in regulating the subthreshold excitability of specific neuronal populations and play a critical role in regulating the frequency and eventual pattern of action potential discharge in many types of neurons. Their importance in neuronal regulation was punctuated by the discovery that neuronal Kv7 mutations lead to benign familial neonatal convulsions (BFNC), demonstrating that reducing or eliminating the influence of Kv7.2 and Kv7.3 channels can dramatically alter neuronal excitability. Mutational analysis demonstrated their involvement in BFNC, suggesting their usefulness as targets for antiepileptic drugs (AEDs).

[0006] Unlike established pharmacological terms for GPCRs, K +The mechanism of action of channel modulators, particularly channel-activating compounds, is still being refined. The application of voltage-clamp techniques to ion channel pharmacology has enabled detailed biophysical studies of whole-cell currents or single channels, allowing for characterization of the nature of compound-channel interactions, but has not prevented continued confusion regarding terminology. The terms opener or activator are commonly used throughout the literature but do not adequately describe the mechanism of action of all these "positive modulator" compounds. Generally, openers or activators are expected to increase the channel's open probability or increase macroscopic current amplitude, but this nomenclature is actually oversimplified. For example, retigabine, the first published Kv7 opener, has a complex and intriguing profile in that it possesses inhibitory activity at higher membrane potentials. Neuronal Kv7 channel openers work in concert with channel activity in the "normal" activation voltage range, enhancing current without significantly affecting the activation threshold, while others can significantly alter the activation threshold. Furthermore, some openers appear to completely eliminate the voltage dependence of activation. Whether these effects represent any continuum is currently unclear, as they are often concentration-dependent. Clearly, the mode of interaction of compounds that may increase channel current is complex and, in most cases, poorly understood, and the impact of these profiles on neuronal responsiveness and system physiology is unclear. Retigabine is a moderately potent, though not highly specific, highly effective opener of Kv7.2, Kv7.5, and heteromultimeric Kv7 channels. Its effect is characterized by a significant increase in channel current over a narrow voltage range. As noted above, the opener is less effective at more positive voltages, and under certain conditions, channel current is significantly reduced at more positive voltages compared to the control current (this "crossover" voltage dependence of opener action is characteristic of many neuronal Kv7 channel openers). This effect is also concentration-dependent, becoming more pronounced at higher concentrations.

[0007] Provided herein are compounds that are potent and / or at least biased toward Kv7.2 / 7.3 heteromultimers over Kv7.4 homomultimers, which may have reduced adverse side effects compared to retigabine. DETAILED DESCRIPTION OF THE INVENTION

[0135] Biological Assays Kv7.2 / 7.3 activation assay

[0136] The ability of compounds to enhance K currents in Kv7.2 / 7.3 containing HEK cells was assessed using planar patch clamp on the QPatch automated screening platform.

[0137] Cell Lines: The hKv7.2 / 7.3 cell line was obtained from Chantest (Cleveland, OH 44128) catalog number CT6147. These HEK cells can be induced to express the Kv7.2 / 7.3 ion channel.

[0138] Cell culture: Cells were maintained in medium containing DMEM / F12 50 / 50 (GIBCO catalog no. 11330), 10% fetal bovine serum (FBS) (GIBCO catalog no. 26140), 100 units / mL penicillin-streptomycin (GIBCO catalog no. 15140), 0.005 mg / mL blasticidin (INVIVOGEN catalog no. ant-bl-1), 0.5 mg / mL geneticin (GIBCO catalog no. 10131), and 0.1 mg / mL zeocin (GIBCO catalog no. R25001). Cells used in electrophysiological assays were maintained in medium without blasticidin, geneticin, or zeocin for 2 days, and channel expression was induced by adding tetracycline (BIOLINE catalog no. BIO-87030) to a final concentration of 1 mg / mL. Cells were grown to approximately 75% confluency in T-175 flasks. Currents were recorded 24 hours after channel induction.

[0139] Compound Plate: Test compounds were plated on a Biomek NX P The external recording solution was prepared by serial dilutions in a BECKMAN COULTER filter. The final dilution was made in the external recording solution with a final DMSO concentration of 0.1% DMSO. For the single-concentration screen, each plate contained 10 μM retigabine as a positive control and 0.1% DMSO as a negative control.

[0140] Electrophysiology: On the day of the experiment, cells were washed with Hank's Balanced Salt Solution (HBBS) (GIBCO Catalog No. 14175) and collected in Triple (GIBCO Catalog No. 12604). Cells were then centrifuged at 2000 rpm for 5 minutes and transferred to CHO-S-SFM (GIBCO Catalog No. 12052) at approximately 3 x 10 6The cells were resuspended at 1000 cells / mL. The cells were stirred for 30 minutes before starting the experiment. The external recording solution contained (mM): NaCl (145), KCl (4), CaCl2 (2), MgCl2 (1), HEPES (10), and glucose (10); if necessary, the pH was adjusted to 7.4 with NaOH and the osmolarity was adjusted to 300-305 mOsM with sucrose. The internal solution contained (mM): KCl (125), KF (10), EGTA (5), Na2ATP (5), MgCl2 (3.2), and HEPES (5); the pH was adjusted to 7.2 with KOH and the osmolarity was adjusted to 298-302 mOsM with sucrose.

[0141] Potassium channel activity was measured using a QPatch HTX (Sofion Biosciences) with a 48-well / plate QP plate. Each cell was used as an independent experiment, and only one compound was tested per well. Potassium channel activity was elicited by holding the potential at -80 mV, stepping to -30 mV for 2 seconds, and then pulse-pulsing the potential to -120 mV for 100 ms.

[0142] Single concentration screen: Baseline conditions were obtained by recording five sweeps with external solution alone, which were repeated for three applications of external solution. The effect of test compound on the evoked current was then assessed by recording five sweeps in the presence of 3 μM compound solution. Steady-state currents were measured at the end of a 2 s pulse to -30 mV to determine the fold increase from baseline.

[0143] Data from the Kv7.2 / 7.3 activation assay are summarized in Table 2. [Table 2] TIFF0007757036000105.tif227149TIFF0007757036000106.tif248150TIFF0007757036000107.tif247147TIFF0007757036000108.tif225159

[0144] The thallium flux assay is used as a surrogate indicator of potassium channel activity.

[0145] The experimental protocol was adapted from the FluxOR™ II Green Potassium Ion Channel Assay User Guide (Publication No. MAN0016084, Invitrogen). Conditions were optimized for the Kv7.2 / 7.3 cell line.

[0146] Cell lines: The hKV7.2 / 7.3 cell line was obtained from Chantest (Cleveland, OH 44128) catalog number CT6147.

[0147] Cell culture: Kv7.2 / 7.3 cells were maintained in medium containing DMEM / F12; 50 / 50 (GIBCO catalog no. 11330), 10% fetal bovine serum (FBS) (GIBCO catalog no. 26140), 100 units / mL penicillin-streptomycin (GIBCO catalog no. 15140), 0.005 mg / mL blasticidin (Sigma 15205), 0.5 mg / mL geneticin (GIBCO catalog no. 10131), and 0.1 mg / mL zeocin (GIBCO catalog no. R25001). One day before the experiment, cells were plated into 96-well clear-bottom plates (Corning catalog no. 353219) in medium without blasticidin, geneticin, or zeocin. Channel expression was induced by adding tetracycline (Bioline catalog number BIO87030) to a final concentration of 10 ng / mL.

[0148] Compound plate: Test compounds are diluted in a mixture of 0.1% DMSO / extracellular solution with an 8-point concentration range from 0.014 μM to 30 μM. Serial dilutions were performed on a Biomek NXP (Beckman Coulter).

[0149] Measurement and Data Analysis: A plate reader (Empire, Perkin Elmer) is used to characterize the ion channel modulation properties of novel compounds using an excitation wavelength of 475 nm and an emission wavelength of 530 nm. After a 15-second baseline measurement, a stimulation buffer containing thallium and potassium is injected. A final endpoint measurement is taken after 90 seconds. Responses are normalized to a positive control (retigabine, up to 30 μM). The mean normalized response at each tested concentration is fit to the standard Hill equation to generate the EC50 and maximum response.

[0150] The thallium flux assay data are summarized in Table 3. [Table 3] TIFF0007757036000110.tif217153TIFF0007757036000111.tif184164

In an embodiment, definite amyotrophic lateral sclerosis is as defined by the El Escorial diagnostic criteria. In an embodiment, the subject has definite ALS, a duration of onset of amyotrophic lateral sclerosis symptoms of less than about 18 months, a plasma creatinine level of about 72 μM / L or greater, concomitant administration of riluzole, concomitant administration of dexpramipexole, and combinations thereof.

[0161] Amyotrophic lateral sclerosis (ALS; Lou Gehrig's disease) is a progressively debilitating motor neuron disease characterized by degeneration and dysfunction / death of upper and lower motor neurons. ALS is universally fatal, but the rate of disease progression may not be linear.

[0162] According to embodiments described herein, the El Escorial World Federation of Neurology's Criteria for the Diagnosis of ALS are as follows (see also Brooks, BR, RG Miller, et al. (2000) "El Escorial revisited: revised criteria for the diagnosis of amyotrophic lateral sclerosis." Amyotrophic Lateral Sclerosis Other Motor Neuron Disord 1(5): 293-9, which is incorporated by reference in its entirety): As used in the El Escorial World Neurological Federation criteria for the diagnosis of ALS, the term "definite" means that certain clinical exclusion criteria are met and no other diagnosis is possible based on clinical distribution or laboratory findings; the term "dementia" is intended to mean progressive deterioration of specific cognitive functions; the term "onset" means the time of subjective symptoms first noticed by the patient and later confirmed by testing; the term "possible" is intended to mean that certain clinical and exclusion criteria are met; the term "probable" is intended to mean certain clinical and exclusion criteria; and the term "worsening" is intended to mean increasing muscle weakness in previously affected body segments or new weakness in previously unaffected body segments.

[0163] The diagnosis of ALS requires the presence of the following: 1) signs of lower motor neuron (LMN) degeneration by clinical, electrophysiological, or neuropathological examination, 2) signs of upper motor neuron (UMN) degeneration by clinical examination, and 3) progressive spread of signs within a region or to other regions in addition to the absence of electrophysiological evidence of other disease processes that might explain the signs of LMN and / or UMN degeneration and the absence of neuroimaging evidence of other disease processes that might explain the observed clinical and electrophysiological signs.

[0164] Furthermore, the El Escorial World Federation of Neurological Associations (ELSE) criteria for the diagnosis of ALS stipulate the following steps in the diagnosis of amyotrophic lateral sclerosis: 1) A medical history, physical, and appropriate neurological examination to confirm clinical findings that may suggest suspicious, possible, probable, or definite ALS; 2) Electrophysiological testing to confirm LMN degeneration in clinically involved areas, identify LMN degeneration in clinically uninvolved areas, and confirm findings that may rule out other disorders; 3) Neuroimaging to confirm findings that may rule out other disease processes; 4) Laboratory testing, as determined by clinical testing, to confirm the possibility of an ALS-related syndrome; 5) Neuropathological testing, as needed, to confirm or exclude sporadic ALS, coexisting sporadic ALS, ALS-related syndromes, or ALS variants; and 6) Repeat clinical and electrophysiological testing at least 6-month intervals to confirm evidence of progression.

[0165] Definite ALS is defined clinically only by the presence of UMN and LMN signs in the bulbar region and at least two other spinal cord regions, or by the presence of UMN and LMN signs in three spinal cord regions. In the absence of electrophysiological, neuroimaging, and clinical testing, the key determinant for the diagnosis of definite ALS is the combined presence of UMN and LMN signs in multiple regions.

[0166] Probable ALS is defined on clinical grounds alone by UMN and LMN signs in at least two regions. The regions may vary, but some UMN signs must be rostral (above) to LMN signs. Several different combinations of UMN and LMN signs may be present in patients with probable ALS.

[0167] Possible ALS is defined on clinical grounds alone when UMN and LMN signs are present in only one region, or when UMN signs are present in two or more regions, or when LMN signs are rostral to UMN signs (the distribution of the latter signs must be distinguished from multiple non-ALS processes). Monomeric ALS, progressive bulbar palsy without spinal UMN and / or LMN signs, progressive primary lateral sclerosis without spinal LMN signs, and progressive primary lateral sclerosis without spinal LMN signs are unique cases that develop LMN or UMN signs and meet the criteria for probable ALS over time or are confirmed by specific LMN and UMN neuropathological findings at subsequent autopsy.

[0168] Suspected ALS reveals only LMN signs in two or more areas, but UNN pathology may be demonstrated at autopsy, although at the time of diagnostic evaluation, only clinical signs are considered relevant to this classification.

[0169] The clinical manifestations of progressive LMN and UMN degeneration seen in ALS may occur 1) in isolation (sporadic ALS), 2) incidentally in association with other pre-existing disease processes that do not occur in parallel with ALS (concomitant sporadic ALS), 3) in association with laboratory-defined or epidemiologically-defined abnormalities temporally linked to ALS (ALS-related syndromes), or 4) in association with clinical, genetic, or epidemiological features that occur in parallel with ALS (ALS variants).

[0170] While physical and neurological examinations allow for a clinical diagnosis of ALS with a certain degree of certainty as defined above, clinical examination must incorporate factors such as disease history, toxic exposure, past medical history, injury history, family history, and geographic location when determining whether a patient has an ALS-related syndrome or an ALS variant.

[0171] ALS-related syndromes must meet clinical, electrophysiological, and neuroimaging criteria for possible, probable, or definite ALS. ALS-related syndromes have distinctive laboratory- or epidemiologically-defined features that are temporally linked to the onset of the ALS phenotype. If correction of the relevant laboratory-defined features does not result in a correct ALS phenotype, patients with ALS-related syndromes should be considered in the same manner as patients with sporadic ALS.

[0172] ALS-related syndromes include: 1) monoclonal gammopathy (e.g., monoclonal gammopathy of undetermined significance, Waldenströms macroglobulinemia, osteosclerotic myeloma), 2) motor system degeneration of immunodeficiency (e.g., autoimmunity; high-titer GMI ganglioside antibodies), 3) non-malignant endocrine abnormalities (e.g., hyperthyroidism, hyperparathyroidism, hypogonadism), 4) lymphoma (Hodgkin lymphoma and non-Hodgkin lymphoma), 5) infections (e.g., HIV-1, HTLV-1, lethargy, encephalitis, varicella-zoster, brucellosis, cat-scratch disease, Creutzfeldt-Jakob disease, syphilis, post-polio syndrome, etc.), 6) acquired enzyme deficiencies (e.g., detoxification enzymes), 7) exogenous toxins (e.g., lead, mercury, arsenic, thallium, cadmium, manganese, aluminum, organic pesticides, lupine seeds), 8) physical injuries (e.g., electric shock, radiation therapy), 9) vascular (vasculitis; ischemic (e.g., Dejerine anterior ophthalmic artery syndrome), 10) spondylotic myelopathy (painless myelopathy without sensory signs, stabilization, or postoperative progression).

[0173] ALS variants must meet clinical, electrophysiological, and neuroimaging criteria for possible, probable, or definite ALS. Although the primary symptoms are those seen in sporadic ALS, multiple phenotypes exist, each characterized by age at onset, location of onset, survival time, and presumed type of inheritance.

[0174] Familial ALS variants in genetic linkage studies should be characterized by an established inheritance pattern spanning at least two generations, at least one clinically unequivocal or autopsy-confirmed case, and convincing evidence excluding other possible causes. Affected subpairs occurring in only one generation may not be attributable to a single gene effect.

[0175] Examples include: a) ALS with defined inheritance and known gene product (hexosaminidase A / B deficiency, superoxide dismutase deficiency); b) ALS with defined inheritance and chromosomal linkage but no gene product (chromosome 21-related familial ALS or chromosome 2-related early-onset familial ALS); c) ALS with defined inheritance and no known linkage or gene product (most cases or familial ALS); d) geographic clustering (disorders seen in the Western Pacific, Guam, Kii Peninsula, North Africa, Madras, etc.) e) signs of bradykinesia (bradykinesia, cogwheel rigidity, tremor, clinically significant onset of supranuclear ophthalmologic signs (tracking abnormalities), familial or sporadic); f) cerebellar degeneration (spinocerebellar abnormalities; familial or sporadic); g) dementia (progressive cognitive abnormalities; familial or sporadic); h) autonomic nervous system involvement (clinically significant abnormal cardiovascular reflexes; bowel or bladder control problems; familial or sporadic); i) objective sensory abnormalities (reduced vibration; sharp and dull discrimination; diminished cold sensation; familial or sporadic); j) electrophysiological features in the diagnosis of ALS.

See, for example, Modern Pharmaceutics, Banker & Rhodes, Marcel Dekker, Inc. (1979); and Goodman & Gilman's The Pharmaceutical Basis of Therapeutics, 6th Edition, MacMillan Publishing Co., New York (1980).

[0320] For oral administration, the compounds of Formulae A-1 to A-44 or B-1 to B-7, or pharmaceutically acceptable salts thereof, can be readily formulated by combining the compounds of Formulae A-1 to A-44 or B-1 to B-7, or pharmaceutically acceptable salts thereof, with pharmaceutically acceptable carriers well known in the art. Such carriers allow the compounds to be formulated in various ways as tablets, pills, dragees, capsules, liquids, gels, syrups, slurries, suspensions, and the like for oral ingestion by the subject to be treated. Pharmaceutical preparations for oral use can be obtained by adding solid excipients, optionally grinding the resulting mixture, adding suitable auxiliary agents as needed, and then processing the granular mixture to obtain tablets or dragee cores. Suitable excipients include, but are not limited to, sugars, including lactose, sucrose, mannitol, and sorbitol; fillers, such as corn starch, wheat starch, rice starch, potato starch, gelatin, tragacanth gum, methylcellulose, hydroxypropylmethylcellulose, sodium carboxymethylcellulose, and cellulose preparations, including polyvinylpyrrolidone (PVP). If desired, disintegrating agents, such as, but not limited to, cross-linked polyvinylpyrrolidone, agar, or alginic acid or a salt thereof, such as sodium alginate, can be added.

[0321] In some embodiments of the various methods, the pharmaceutical composition may be suitable for oral administration, such as, for example, a solid oral dosage form or a capsule, and in certain embodiments, the composition may be a tablet. Such tablets may contain any number of additional agents, such as, for example, one or more binders, one or more lubricants, one or more diluents, one or more lubricants, one or more surfactants, one or more dispersants, and one or more colorants. Such tablets can be prepared by any method known in the art, such as compression or molding. Compressed tablets can be prepared by compressing the components of the composition in a free-flowing form, such as powder or granules, in a suitable machine, while molded tablets can be produced by molding a mixture of powdered compounds moistened with an inert liquid diluent in a suitable machine. In some embodiments, the tablets may be uncoated, while in other embodiments, they may be coated by known techniques.

[0322] In other embodiments, pharmaceutical compositions prepared for oral administration may be provided in dragee cores with suitable coatings. In such embodiments, dragee cores may be prepared using gum arabic, talc, polyvinylpyrrolidone, carbopol gel, polyethylene glycol, and / or titanium dioxide, a lacquer solution, and a concentrated sugar solution that may optionally contain a suitable organic solvent or solvent mixture. In some embodiments, dyes or pigments may be added to the tablets or dragee coatings for identification or to characterize different combinations of active compound doses. In still other embodiments, pharmaceutical compositions prepared for oral administration containing an effective amount of a compound of Formulas A-1 to A-44 or B-1 to B-7 or a pharmaceutically acceptable salt thereof may include, but are not limited to, push-fit capsules made of gelatin and soft, sealed capsules made of gelatin and a plasticizer such as glycerol or sorbitol. Push-fit capsules can contain active ingredients in admixture with fillers such as lactose, binders such as starches, and / or lubricants such as talc or magnesium stearate, and, optionally, stabilizers. In soft capsules, the active compounds can be dissolved or suspended in suitable liquids, such as fatty oils, liquid paraffin, or liquid polyethylene glycols. Additionally, stabilizers can be added. All formulations intended for oral administration should be in dosages suitable for such administration.

[0323] In various embodiments in which tablets and dragee cores are coated, the coating may delay disintegration and absorption in the gastrointestinal tract, thereby providing a sustained action over a longer period of time. Furthermore, such coatings may be adapted to release the compound of Formulae A-1 through A-44 or B-1 through B-7, or a pharmaceutically acceptable salt thereof, in a predetermined pattern, e.g., to achieve a controlled-release formulation, or may be adapted not to release the active compound until after stomach passage, e.g., by including an enteric coating. Suitable coatings for such embodiments may include, but are not limited to, sugar coatings, film coatings such as hydroxypropylmethylcellulose, methylcellulose, methylhydroxyethylcellulose, hydroxypropylcellulose, carboxymethylcellulose, acrylate copolymers, polyethylene glycol, and / or polyvinylpyrrolidone, or enteric coatings such as methacrylic acid copolymers, cellulose acetate phthalate, hydroxypropylmethylcellulose phthalate, hydroxypropylmethylcellulose acetate succinate, polyvinyl acetate phthalate, shellac, and / or ethylcellulose. Additionally, a time delay material, such as, for example, glyceryl monostearate or glyceryl distearate, can be incorporated into the coating in some embodiments. In yet other embodiments, the solid tablet compositions may comprise a coating adapted to protect the composition from unwanted chemical changes, for example, to reduce chemical degradation prior to the release of the active pharmaceutical ingredient.

[0324] Pharmaceutical compositions suitable for oral administration within various method embodiments may comprise a therapeutically effective amount of a compound of Formulae A-1 through A-44 or B-1 through B-7, or a pharmaceutically acceptable salt thereof, and may further comprise one or more diluents, one or more disintegrants, one or more lubricants, one or more pigments or colorants, one or more gelatins, one or more plasticizers, etc. For example, in some embodiments, a tablet may comprise an effective amount of a compound of Formula A-1 to A-44 or B-1 to B-7, or a pharmaceutically acceptable salt thereof, in an amount of about 20% to about 50% by weight of a diluent, about 10% to about 30% by weight of a second diluent, about 2% to about 6% by weight of a disintegrant, and about 0.01% to about 2% by weight of a lubricant; in certain embodiments, such a tablet may comprise an effective amount of a compound of Formula A-1 to A-44 or B-1 to B-7, or a pharmaceutically acceptable salt thereof, about 20% to about 50% by weight of microcrystalline cellulose, about 10% to about 30% by weight of mannitol, about 2% to about 6% by weight of crospovidone or croscarmellose, and about 0.01% to about 2% by weight of magnesium stearate. In further embodiments, the pharmaceutical composition may include any amount or combination of microcrystalline cellulose, mannitol, sodium, crospovidone, croscarmellose magnesium stearate, or any combination thereof.

[0325] In some embodiments of the various methods, pharmaceutical compositions containing a compound of Formulae A-1 through A-44 or B-1 through B-7, or a pharmaceutically acceptable salt thereof, may be prepared as a suspension, solution, or emulsion in an oily or aqueous vehicle suitable for injection. In such embodiments, such liquid formulations may further include formulating agents, such as suspending agents, stabilizers, and / or dispersing agents, formulated for parenteral administration.

[0332] In embodiments, the method further comprises administering one or more active agents simultaneously with or together with administering a compound of Formula A-1 through A-44 or B-1 through B-7, or a pharmaceutically acceptable salt thereof. In embodiments, the one or more active agents are dexpramipexole, riluzole, baclofen, tizanidine, or edaravone. Riluzole is a neuroprotective agent that blocks inactivated sodium channels. Riluzole has been shown to prolong survival in ALS subjects. In embodiments, riluzole is administered at 50 mg once or twice daily. In embodiments, dexpramipexole is administered at a total daily dose of 150 mg, or 300 mg or 600 mg. In embodiments, baclofen is administered at 0.05 mg, 0.5 mg, 1 mg, 2 mg, 5 mg, 10 mg, or 20 mg. In embodiments, tizanidine is administered at 2 mg, 4 mg, or 6 mg. In an embodiment, edaravone is administered at 30 mg. In an embodiment, the one or more active agents is dexpramipexole. In an embodiment, the one or more active agents is riluzole.

[0333] In embodiments, the one or more active agents are antiglutamate or ion channel blockers, such as, but not limited to, FP-0011, memantine, N-acetyl-α-linked acidic dipeptidase (NALADase) inhibitors, nimodipine, or combinations thereof. Excessive glutamate levels have been shown to be toxic to neurons, and evidence suggests that both direct and indirect glutamate toxicity may contribute to the pathogenesis of motor neuron degeneration in diseases such as ALS. FP0011 is an antiglutamatergic compound that can reduce presynaptic glutamate levels and exhibits potent neuroprotective properties. Memantine is a noncompetitive N-methyl-d-aspartate (NMDA) receptor antagonist that has been shown to protect neurons from NMDA- or glutamate-induced toxicity in vitro and in animal models of neurodegenerative disease. In some embodiments, memantine is administered at 2 mg, 5 mg, 7 mg, 10 mg, 14 mg, 21 mg, or 28 mg. N-acetylated alpha-linked acidic dipeptidase (NAALADase) converts N-acetyl-aspartate-glutamate to glutamate during neuronal injury, potentially representing a novel approach to block excess glutamate release without interfering with normal brain function in the treatment of neurodegenerative disorders. Nimodipine is a dihydropyridine calcium channel blocker that antagonizes the activation of excitatory amino acid receptors, reducing calcium influx into damaged neurons and potentially helping to slow or reverse ALS. In some embodiments, nimodipine is administered at 30 mg or 60 mg.

[0334] In embodiments, the one or more active agents are mitochondrial energy promoters, such as, but not limited to, resveratrol, creatine, erythropoietin, cholest-4-en-3-one, oxime (TRO-19622), and combinations thereof. Resveratrol is a potent antioxidant found in red grape skin and has been shown to inhibit calcium influx into cells, which is associated with glutamate-induced cytotoxicity. In embodiments, resveratrol is administered at 100 mg, 500 mg, 1000 mg, or 1500 mg. Creatine has been shown to aid in the formation of ATP, the body's primary source of cellular energy, provide a protective mechanism against neurodegenerative disorders by stabilizing cell membranes and mitochondrial energy transduction complexes, and may reduce motor neuron death by improving mitochondrial function. Creatine also reduces oxidative stress and increases glutamate uptake, potentially helping to alleviate muscle weakness in ALS patients. In embodiments, creatine is administered at about 750 mg to about 5 grams. Erythropoietin (EPO), a glycoprotein hormone that regulates red blood cell production, has recently been identified as a cytokine with various neuroprotective effects, including reducing inflammation, enhancing survival signals, and preventing neuronal cell death. Cholest-4-en-3-one, oxime (TRO-19622), is a low-molecular-weight compound that has been shown to promote motor neuron survival and growth by interacting with protein components of the mitochondrial permeability transition pore and potentially rescue motor neuron cell bodies from axon-induced cell death in vivo. In embodiments, the one or more active agents is creatine. The present application also includes the following aspects.
